Abstract


Background: The goal of the present investigation was to evaluate docetaxel (DOC)-loaded gelatin nanoparticles
for cancer therapy. Materials and Methods: DOC-loaded gelatin nanoparticles using ultraviolet-visible
spectroscopy, X-ray diffraction, particle size and size distribution, scanning electron microscopy, drug entrapment
efficiency, infrared, and in vitro drug release were characterized. The viability of MCF-7 breast cancer (BC) cells
was determined by MTT. Cell sensitivity to drugs and growth curves were measured by MTT assay. Changes
of cell morphology and ultrastructure were examined by optical and electron microscopy. Results: Solubility,
crystallinity, and the crystal properties of an active pharmaceutical ingredient play a critical role in the value
chain of pharmaceutical development, manufacturing, and formulation. The rate of drug release for formulation
stored at 45°C ± 1°C was increased as compared with the fresh formulation; it might be due to the formation of
more pores in the nanoparticles due to evaporation of residual amount of solvent. The in vitro release studies of
drug-loaded nanoparticles were conducted at 37 ± 0.5 and 100 rpm using phosphate buffer pH 7.4 (900 ml) in a
USP dissolution apparatus under sink condition. DOC-loaded gelatin nanoparticles depleted the viability of MCF
human breast cell line. In this study, MCF BC cell line revealed growth inhibition in a dose-dependent manner
when treated DOC-loaded gelatin nanoparticles at concentrations ranging from 5 to 100 μg. Conclusion: The
DOC-loaded gelatin nanoparticles displayed differential cytotoxicity toward MCF7 cancer cells. These biogenic
nanoparticles are biocompatible and found to be good candidates for sustained drug delivery in diseases like
cancer.
